Reaction Steps

A mixture of 1-methyl-5-(2-morpholin-4-yl-[1,2,4]triazolo[1,5-a]pyridin-7-ylcarbamoyl)-1H-pyrazole-4-carboxylic acid (100 mg, 0.269 mmole), cyclopentyl-methylamine (107 mg, 1.08 mmole), N-ethyldiisopropylamine (376 ul, 2.15 mmole) and 1-propanephosphonic acid cyclic anhydride (50% in ethyl acetate, 404 ul, 0.673 mmole) in tetrahydrofurane (4 ml) was stirred for 22 hours at 70° C. The solvent was evaporated, the residue was triturated with sodium hydrogencarbonate solution. The precipitated solid was filtered off, washed with water and dried affording N4-cyclopentyl-N4,1-dimethyl-N5-(2-morpholino-[1,2,4]triazolo[1,5-a]pyridin-7-yl)-1H-pyrazole-4,5-dicarboxamide (113 mg, 92.7%) as an off-white solid. mp.: 222-4° C., MS: m/z=453.5 (M+H+)
